/ CLOTH-CUTTING MACHINE.

SPECIFICATION forming part 0f Letters Patent No. 359,570, dated March 15, 1887. Application filed January 15,1887. Serial No2-24,422. (No model.)

To all whom it may concern-.-

Be it known that I, PATRICK Howe, of Boston, county of Suffolk, and State of Massachusetts, have invented an Improvement in 5 Cloth-Cutting Machines, of which the following description, in connection with the accompanying drawings, is a specificatiomlike letters on thedrawings representing like parts.

This invention is an improvement upon Letxo ters Patent of the United States No. 355,086,

dated December 28, 1886, and has for its object to improve the construction ofthe rotatable cutter-carrying head and its attached parts, whereby the said head may be revolved manu 1 5 ally and without lost motion on an axis at right angles to the axis of the shaft carrying the cutter.

This invention in cloth-cutting machines consists of a frame moved by the swinging 2o arms and a rotatable cutter-carrying head carried by the said frame, the cutter and its shaft, and means for rotating the cutter-carrying shaft, combined With a rod passingvertically through the said frame and positively con- 2 5 nected at its lower end with the said head, and means for manually rotating the rod,whereby the said head supporting the cutter and its shaftmay be rotated positively.

The invention also consists in the combinao tion, with the rotatable head and cutter carried by it, of a shoe having a yielding lip, which lip bears upon thetable as said head is moved, the said lip compensating for inequalities in the surface of the table.

Figure l shows in vertical section the frame, the rotatable head and cut-ter, and attached parts" of a cloth-cutting machine, sufficient to illustrate this present invention; Fig. 2, a cross-section of the parts shown in Fig. 1,taken 4o on the dotted line x ac,- and Fig. 3,21 side elevation of the shoe detached.

The tubular swinging arm aihas a hollow frame, c', screwed into it, said hollow frame containing the two intermeshing beveled gears 45 c a3, one of which, as a2, is secured to a rotating shaft, a", contained within the tubular swinging arm a, while the other, as a3, is secured to a tubular shaft, a5,which latter passes vertically throughthe frame a'. The lower end of the tubular shaft a5 has secured to it a 5o beveled gear, a, which meshes with a beveled gear, al, secured to a shaft, as, having its bearings in a head, b, rotatable upon the frame a',

`the said shaft as having xed to it the rotary cutter a.

The parts thus far described are quite analogous to the parts represented in the patent referred to.

A cap, d, rest-s upon a flange, d', projecting laterally from the upper end of the frame a', 6o and a handle or bar, di, is secured to the shank of the said cap d by a screw, d3, so that the said cap may be'rotated freely upon the frame. A suitable latch or dog, Z, is attached to an arm, Z', located at the under side of the handle-bar d2, 6 5 which latch or dog engages one or another tooth of a series ofy teeth, as c, out in the upper side or end of the frame a. when the hand is removed from the handle or bar d2. A rod, e, is secured to the bar cl2 by a pin, e', said rod ex- 7o tending downward vertically through the end plate, di, of the frame a, the frame, and also through the tubular shaft a5, the lower end of the said rod e being secured to a plate, e3, which is rigidly attached to the interior of the 7 5 rotatable head b, so that as the rod e is rotated by the handle or bar d2 the head b will be ro tated, thereby rotating the cutter about the shaft e as an axis.

By the employment of the rod e a positive 8o connection is made with the head b, so that the said head may be rotated without material loss of motion, thus overcoming a difficulty which has been found somewhat objectionable in the patent referred to. 8 5

A shoe, s, having a shank, s', secured to the rotatable head b by a set-screw, bx, (see Fig. 2,) has a yielding lip, s, secured to its forward end, the said lip bearing upon the table upon which the cloth is laid, the yielding ac- 9o tion of the lip enabling it to compensate for the many inequalities of tables, so that the shoe will not in passing over the table occasionally leave one or two thicknesses of cloth, as now sometimes happens with shoes of ordi- 9 5 nary construction.

It is obvious that instead of joining the rod e with the head in the manner herein shown it may be joined in any other way, directly or indirectly.

I claim" l. In a cloth-cutting machine, the swinging arm, the frame carried by it, the rotatable head turning on the frame, the cutter, the cut-- ter-carrying shaft supported by the rotatable head, and means for rotating the said shaft, combined with the rotatable rod e, extending` vertically through the frame and connected with the head, whereby rotation is imparted to the head, substantially as described.

2. In a cloth-cutting machine, the arm, the frame carried by it, the rotatable head, the cutter,and the cutter-carrying shaft supported by the rotatable head, a rotating tubular shaft,

afor rotating the cutter-carrying shaft, combined with the rotatable rod e, passing vertii cally through the shaft a5 and connected with the head for turning the head on an axis at 2o right angles to the axis of rotation of the cutter-carrying shaft, substantially as described.

3. In a cloth-cutting machine, the head and cutter and cutter carrying shaft, combined with the shoe s, connected with the head, and 2 j a lip, s2, composed of a iiexible piece of metal ixed to the forward end of the shoe, all substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two sub- 3o scribing witnesses.

PATRICK HOVE.
